Alex Kwechansky is a Forensic Accountant, which I think is about as sexy as accounting gets.  After large amounts of money have been stolen from large companies, Alex recreates the events that lead up to the theft.  He interviews witnesses, he analyses financial anomalies in the data, and he follows his gut.  You need three things:  Motivation, credibility, and an opportunity.  This is just like investigating a homicide.  Alex explains all the clever ways in which businesses are cheating their employees, their customers, and each other!  We talk about the blurry line between unethical and illegal, the sadistic brilliance of Enron, and whether or not he is a rehabilitated criminal mastermind.
